INVESTIGATION  OF THE PLATE TEMPERATURE FIELD IRREGULARITY INFLUENCE  ON THE METAL STRESS-STRAIN STATE  IN THE DEFORMATION ZONE DURING PLATES ROLLING

The plate cross section temperature gradient and the behavior of plate height temperature distribution influence on the metal stress-strain state in the deformation zone was shown in this work with the help of mathematical modeling methods. It was found, that it is possible to control the behavior of the stress-strain state by creating a certain temperature gradient to avoid the tensile stress in the high deformation zone central part and to reach high strain of central metal layers.
